1,500 ft·lb is the number most repeated (Guns & Ammo, Backfire); Hawks says 1,200, Boddington floats 2,000. Avoid quick-opening and match bullets. Legal: SD: ≥ .243 and 1,700 ft·lb at muzzle · CO: 1,000 ft·lb at 100 yd, ≥ 85 gr. Floor used: 1,500 ft·lb at impact plus the bullet's published expansion velocity. Orange = a target or varmint bullet (construction, not energy); red = never carries the energy. Sources: www.gunsandammo.com, www.chuckhawks.com, www.petersenshunting.com, regulations.justia.com.
